Surface high pressure will keep dry weather in the forecast through today as a cut-off low churns into the southeast U.S. This low will have little impact to the area in the near term, adding only some mid and upper level clouds to our mountain zones through the evening. Any rain chances look to hold off until after sunset tonight. Abundant sunshine through the day will result in high temperatures topping out a few degrees above normal.
